SHOVEL .ATTACHMENT FOR TOBACCO CULTIVATION.

To f/,ZZ wim/m it may concern:

Be it known that I, RAYMOND GRINDE, a citizen ot' the United States, residing at, WaunakeeI` in the county of Dane and State ot lVisconsin, have invented certain new and useful Improvements in Shovel Attachments for rlrobacco Cultivation; and I do hereby declare the following to be a full, clear, and exact description ot' the invention, such as will enable others skilled in the art to which it appertains to make and use the sameI- reference being had to the accompanying drawings, and to the letters and tigures of reference marked thereon, which form a part of this specification.

This invention relates to new and useful improvements in attachments to straddle row culti atei-s, especially adapting the apparatus for hoeing tobacco plants, etc.

The invention comprises various details ot' construction and combinations and arrangements ot parts which will be hereinafter fully described, shown in the accompanying drawings and then specifically detined in the appended claim.

.l illustrate my invention in the accompanying drawings, in which Figure l is a view in elevation showing` the frame of a cultivator with my invention applied thereto. vFig. 2 is a rear view, and Fig. 23 isa detail sectional view taken on line 3-3 of Fig. l.

Reference now being had to the details of the drawings by letter, A designates the t'rame ot` an ordinary straddle row cultivater B with seat D supported upon a bar fastened at` its ends to the frame. The drop axle has journaled thereon the wheels k2. Depending from the trame are the bars (l. having their lower ends bent lateraltv as at C torining bearings for the crank arms C2 which are journaled thereon. Coiled springs, designated by letters C3, are tastened, eacn at its lower end, to the arms C2 and the upper end ot' each is t'astened to the trame ot' the cultivator.

Cultivators F are mounted upon standards E and are arrznged in series and tasten-ed together, one beam of each series being pivotally mounted upon the laterally projecting bearing portion C of the bars C and fastened to the crank arms C2, thereby af- Speccation of Letters Patent.

fording a resilient connection between the beams and the cultivator frame. Fastened to one beam ot' each series is a rod H, the upper end ol which is threaded and passes through a threaded opening in the beam, as shown in Fig. 3 ot' the drawings, and is held by means of a nut. fl'. The lower end of each rod H is spherical shaped as at H and has a bearing in the two blocks K and N, which latter is provided with a threaded opening tor the reception of the threaded end of the rod N each rod N has fixed thereto a collar 0 from which an arm O projects which carries a hoe ll. The rods S have collars f" fixed to their lower ends and which are held by set screws upon the rods N, the upper end ot each rod S having av laterally pro jecting handle portion S2, :forming means whereby the rods may loe raised or lowered, it t'lesired, by the operator sitting` upon the seat l).

By the provision ot' a cultivator attachment made in accordance with my invention, it will be noted that the two series ot' cultivator beams and also the rod supported thereby are held under tension of the springs normally in the positions shown in the drawings, the cultirators yielding when coming in contact with obstructimis and, thronc'h the medium ol: the operating rods S, til/ie upper ends ot' which are convenient to the operator upon the seat. the rods N may be raised indepeinlent of the beams by reason of the ball and socket joint intermediate the lower spherical end ot the rods H and the bearing in one oitl which thc t'orward ends ot' the rod N arc mounted.
